Description

Technical Field

[0001] The utility model relates to the technical field of PVC decorative film conveying racks, in particular to a PVC decorative film production conveying rack with a limiting function. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow, translucent and shiny. Printing different colors or patterns on the surface of the PVC film makes it a PVC decorative film. During the processing and production of the decorative film, it needs to be operated or transported through a transmission frame.

[0003] The conveying racks in the existing technology are all conveyed by conveying rollers. However, due to winding and releasing during the conveying process, the PVC decorative film may be easily wrinkled, thereby affecting the appearance and quality.

[0004] The existing patent (Announcement No.: CN214692448U) discloses a conveyor rack for the production of PVC decorative films. When the automatic telescopic rod is started, the rack drives the gear to rotate. The two gears are meshed with each other, which can make the bearing at the center of the gear rotate, thereby driving the two swing blocks to rotate. The swing blocks begin to swing back and forth on the conveyor belt through the extension and contraction of the automatic telescopic rod, and perform an extension operation. In conjunction with the protective block, wrinkles of the decorative film can be reduced.

[0005] In response to the above problems, although the solution given in the existing patent can scrape the decorative film to avoid wrinkles through the cooperation of components such as automatic telescopic rods, in actual use, the decorative film is repeatedly pulled and transported by components such as active wheels and pressure plates to keep it flat, which may cause pulling at both ends at the same time, resulting in the pulling force causing the decorative film to stretch, and the overall thickness of the decorative film will become thinner, affecting the quality of the product. Summary of the invention

[0006] The purpose of the utility model is to provide a PVC decorative film production conveyor rack with a limiting function, which can avoid deformation of the decorative film caused by multiple and multiple end pulling and affect the quality, so as to solve the problems raised in the above background technology.

[0028] By adopting the above technical solution, the support frame 2 is used to support the conveying roller 3 to convey the decorative film, and after passing through the mounting block 402 through the placement groove 403, it enters the conveying box 1 through the conveying port 6, and the decorative film is limited by the mounting block 402 and the placement groove 403 during the conveying process to avoid deviation or shaking. The mounting block 402 is pushed by the hydraulic rod 401, so that the roller 406 and the rubber pad 407 rotate to contact the decorative film, and tension is performed while conveying to avoid looseness and wrinkles. The rubber pad 407 is used to prevent excessive compression and stretching of the decorative film. The rubber scraper 405 at one end of the support plate 404 fits the decorative film during the conveying process to level it to avoid repeated pulling and damage to the decorative film. The conveying box 1 prevents the vacuum cleaner main body 5 from excessively spreading the vacuum on the decorative film.

[0029] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a cleaning mechanism 7 is provided on one side of the hydraulic rod 401, and the cleaning mechanism 7 includes a connecting plate 701, which is fixed to the outer wall of the hydraulic rod 401, and one end of the connecting plate 701 that penetrates into the conveying box 1 is connected to a fixed shell 702, and a bearing cylinder 703 is rotatably connected to the lower part of the fixed shell 702. The cleaning mechanism 7 also includes a damping spring 704, which is embedded in the upper part of the fixed shell 702, and one end of the damping spring 704 is connected to an upper brush 705, and a lower brush 706 is embedded in the lower part of the fixed shell 702 at a position corresponding to the upper brush 705. The upper brush 705 forms an elastic structure with the fixed shell 702 through the damping spring 704, and the upper brush 705 fits tightly with the lower brush 706. Limiting grooves 8 are provided on both sides of the interior of the conveying box 1, and sliding grooves 9 are provided on the outer wall of the conveying box 1 at a position corresponding to the connecting plate 701.

[0030] By adopting the above technical solution, when the mounting block 402 adjusts its position, the connecting plate 701 follows the control of the hydraulic rod 401 to adjust its position, thereby preventing the fixed shell 702 from pulling and damaging the decorative film. The decorative film passes through the fixed shell 702 and is stably conveyed under the rotational resistance of the two supporting cylinders 703. The damping spring 704 elastically pushes the upper brush 705, which clamps the decorative film with the lower brush 706 and cleans and scrapes off the dust on the surface. The limiting groove 8 facilitates the stable sliding of the fixed shell 702, and the sliding groove 9 facilitates the stable sliding of the connecting plate 701, thereby maintaining stability and avoiding deviation that affects the conveying of the decorative film.

[0031] Working principle: The conveying roller 3 connected by the support frame 2 is rotated to facilitate the supporting decorative film to penetrate the installation groove 403 of the installation block 402, and then enter the interior of the conveying box 1 through the conveying port 6. The hydraulic rod 401 pushes the installation block 402 so that the roller 406 and the rubber pad 407 rotate to contact the decorative film for tensioning, and cooperates with the installation groove 403 to limit the decorative film. At the same time, during the conveying process, the rubber scraper 405 bonded by the support plate 404 presses the decorative film to achieve a leveling effect, and enters the vacuum device body 5. Dust is sucked away to avoid dust absorption. After the decorative film enters the conveying box 1, it passes through the fixed shell 702. The fixed shell 702 is driven by the hydraulic rod 401 through the connecting plate 701, and slides along the sliding groove 9 following the mounting block 402. The fixed shell 702 stably conveys the decorative film through the internal bearing tube 703. At the same time, the upper brush 705 is pushed by the damping spring 704, and the decorative film is clamped and cleaned in cooperation with the lower brush 706. The fixed shell 702 slides axially in the limiting groove 8 at both ends to avoid deviation and shaking.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
